Let me get some of that,while candy was being passed around at summer camp two anonymous teenagers allegedly over heard a large girl who couldn't wait her turn rudely say "let me get some of that". From then on she was known as LMGSOT. It can also mean anything good or anything bad. But when it is used in a negative context is is used sarcastically.

When you're being horny (especially around friends) and as a result shame ensues.
